Ethanol (G1.0 / G1.5 / G2.0)

G1.0, G1.5 & G2.0 ethanol and high-value co-products, with no food vs fuel debate

Feedstocks
G1.0 & G1.5: non-edible grains (corn, rice, wheat, sorghum), cassava, potatoes, sugar cane juice / molasses, and other agricultural productsG2.0: biomass, agricultural waste, corn stover, sugar cane bagasse, sweet sorghum bagasse, wood chips, forestry and paper waste
Products
G1.0 & G1.5: advanced ethanol, with biogenic CO₂, DDGS, and corn oil as co-productsG2.0: cellulosic ethanol, with biogenic CO₂ as co-product plus lignin and syrup as biofuel for cogen
Maturity
Commercial (through partnership)
Ethanol (G1.0 / G1.5 / G2.0)

Besides the use of non-edible grain, sugarcane, and molasses, cellulosic, or second-generation (2G), ethanol turns non-food biomass into low-carbon ethanol, the feedstock that powers Petron’s renewable chemicals and fuels without competing with food crops.

Petron’s solution & differentiators

Licensable, state-of-the-art non-edible grain and biomass-to-ethanol technologies, commercially proven, highly integrated, and with the best yields in the current market.

Applicable feedstocks & products

Agricultural crops and crop residues, biomass and forestry residues, dairy waste, and non-edible grains such as sorghum and sugarcane, as well as molasses and other cellulosic feedstocks (including sugarcane and sorghum bagasse, corn cob and stover, wood, and agricultural wastes like rice and wheat straw, husk, and bran), can all be efficiently used as raw materials in Petron’s 1.5 and 2.0 generation technologies. These processes produce ethanol of all grades for biofuels, green chemicals and polymers, and a wide range of industrial, pharmaceutical, food, and alcoholic-beverage applications. Biogenic CO₂ is generated from fermentation in both generations. In addition, Generation 1.0 and 1.5 plants co-produce DDGS and corn oil, while Generation 2.0 plants generate lignin and syrup, which are used internally as fuel to supply the heat and power required by the process.

Commercial maturity

Commercially deployable; a cornerstone of the integrated biorefinery offering.

How it works

Process block diagram

G1 versus G2 ethanol process: the G1.0 and G1.5 grain route and the G2.0 cellulosic route, each running from feedstock through conversion, fermentation, and distillation and dehydration to fuel ethanol, with biogenic CO2 from fermentation, DDGS and corn oil co-products on the grain route, and lignin and syrup bioenergy co-products on the cellulosic route.
